WATCHCASE AND DIAL.

Application filed November 10, 1922.

To (ZZZ whom it may concern:

Be it known that we, lllAURICE A. Forum, and JACOB ScHoNHoLTz, citizens of the United States, residing at New York city. in the county of New York and State of New York have invented new and useful Improvements in Watchcases and Dials, of which the following is a specification.

This invention relates to the class of horology and particularly to watch cases and dials and has for its primary object the provision of means forming an integral part of the case adapted to directly co-act with a dial to secure the same in position upon the case. In the art of manufacturing watches. it is customary to provide the works of the watch with means co-acting with the dial to secure the latter in its relatively fixed position of adjustment. The disadvantage of an arrangement of this character resides in the fact that a dial of a given size and character can only be made to adapt itself to watch works of a mating construe tion and size. Should the owner of the works of relatively small size desire to mount same in a case of an appreciably larger size, this cannot be accomplished with the well-known forms of dials and works.

It is therefore an important object of our invention to provide a case and co-acting dial which will satisfactory permit same to accommodate themselves to watch works of varying types and sizes and to bring about an arrangement of parts whereby the necessity of securing the dial upon the works of the watch is entirely eliminated.

A still further object of the invention is to provide an arrangement of this character which can be incorporated in the construction of thin watch cases without detracting from the beauty thereof.

A still further object of the invention is to provide a device of this character which from the nature of its construction will constitute a double guard to protect the case from dust and moisture.

With these and other objects in view. the invention resides in certain novel construction and combination and arrangement 01 parts, the essential features of which are hereinafter fully described. are particularly pointed out in the appended claim. and are Serial No. 600,087.

illustrated in the accompanying drawing, in which Figure 1 is a plan view of the case with the dial removed.

Figure 2 is a sectional view of the dial.

Figure 3 is a transverse section through the watch with the dial and crystal occupyin their normal positions.

.n carrying the invention into practice, we make use of a thin case 5 closed at one side as at 6 and open at its opposite side at 7. The said opposite side is provided with a circular dial ledge 8 which is undercut along its periphery at 9 and arranged in concentric relation with a circular undercut surface 11 which extends around the margin of the case and which is adapted to receive the crystal frame 12 in the usual manner.

The dial 13 may be constructed of metal or any suitable well-known stiff material and same is provided with a resilient or springy rim 1% adapted to be snapped into position against the undercut surface 9 of the aforesaid ledge 8. In this manner it will be observed that the dial is firmly held in its posi tion of adjustment upon the case and that it is not necessary to secure the dial to the works of the watch. Works of varying sizes can be secured in any suitable wellknown manner in the case with its hand arbor posi tioned in line with arbor perforation 15 in said dial.

By providin the dial 13 with an annular resilient rim 14 and by positioning the same in concentric relation to the portion 11 which receives the crystal it follows that when the crystal is applied to the case it co acts with the dial to constitute a double dust and moisture guard. It will be further understood that from the nature of construction and arrangement of parts. the operation of adjusting the dial to or removing the same from the watch may be carried on with dispatch and convenience.

hile we ha e described what we deem to he the most desirable embodiment of our invention. it is obvious that many of the details may be varied without in any way departing from the spirit of our invention, and we therefore do not limit ourselves to the exact details of construction herein set forth nor to anything less than the whole of our invention limited only by the appended concentric with the first named portion for claim. accommodating a crystal frame.

What is claimed as new is In testimony whereof We have afl'ixed our 10 A watch case provided with an annular signatures. 5 undereet ortion, and a dial biv-i plg a ne silient annular rim engageable with said JACOB $CHQNHQLTZ. portion, the case having a second portion MAURICE A. POPIEL.
